Abstract

ZALDIVAR, Belén et al. Use of habitat and activity patterns of white lipped (Tayassu pecari) and collared (Pecari tajacu) peccaries in cattle ranching environments of the Dry Chaco, Paraguay. Rep. cient. FACEN [online]. 2022, vol.13, n.1, pp.20-27. ISSN 2222-145X.  https://doi.org/10.18004/rcfacen.2022.13.1.20.

The white lipped peccary is gregarious with herds of up to 300 individuals and it lives in humid and xerophytic forests. The collared peccary forms groups of up to 50 individuals and shows great ecological plasticity due to the variety of environments it lives in. Both species are seed predators and natural prey for carnivores. They are faced by threats such as loss and fragmentation of habitat and poaching. This investigation’s objectives were: (1) to contribute to the knowledge on the distribution and occupation of T. pecari and P. tajacu in relation to landscape characteristics, (2) to describe activity patterns in productive landscapes in the Paragua- yan Dry Chaco. 45 sampling stations were established at Estancia Montania (Boquerón Department, Paraguay). A camera trap was placed at each station from 2015 to 2017. Each camera was placed on a wildlife trail. The photographs obtained were classified and analyzed using program (DataOrganize and DataAnalyze). T. pecari registered greater use in places with more forest coverage due to the higher availability of food. P. tajacu did not demonstrate significant differences in habitat use with respect to forest coverage. The behavioral patterns of the species do not show temporal segregation.
